BOlLER-FLUE CLEANER.

SPECIPICATION forming part of Letters Patent No. 310,549, dated January6, 1885.

Application filed May 12, 1884. (Xo model To all, whom zit may concern.-

Be it known that I, JAMES R. Wooowon'rn, a citizen of the United States,and a resident of Nunda, in the county of Livingston and State of NewYork, have invented certain new and useful Improvements in BoilenFlueCleaners; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification, and in which Figure 1 is a perspective view of myi1nproved steam-boilerflue cleaner, and Fig. 2 is a longitudinal sectionof the same, showing it inserted into the end of aflue, the flne-sheetand fine of the boiler being shown in section.

Similar letters of reference indicate corresponding parts in both thefigures.

My invention has relation to that class of line-cleaners forsteam-boilers in which steam is injected into the flue, carrying thesoot and dust away; and it consists in the improved construction andcombination of parts of the same, as hereinafter more fully describedand claimed.

In the accompanying drawings,'the letter A indicates the flue-sheet, andB one of the lines; and the letter 0 indicates a funnelshaped nozzleadapted to be inserted into the end of the flue, and provided with atube, 1), projecting from the inner side of the aperture E in the end orapex of the cone, which tube has a longitudinal slot, F, and two lips,G, at its rear end. A tube, H, having a handle, I, at its rear end, andhaving a T-joint, J, in1- mediately in front of the handle, which jointis provided upon its laterally-projecting arm with a hose, K,communicating with the boiler and carrying steam from the same, slideswith its forward end inside the tube projecting from the inner side ofthe nozzle, and has a screw, L, near its forward end, which projects upthrough the slot in the nozzle-tube,

sliding in the same, and serves to prevent the sliding pipe from slidingtoo far into or out of the nozzle-tube. A spiral spring, M, is

wrapped around the sliding tube to the rear of the nozzle-tube, bearingwith its forward end against the rear end of the nozzle-tube, andhearing with its rear end against a collar, N,

secured adj ustabl y, by means of a setscrew, 0, upon the sliding pipe.A handle, 1?, of any desirable non-conducting material, is secured uponthe sliding steanrtube, and a stopcock, O, is immediately to the rear ofthe said handle, and is provided with an arm, R, to the end of which aeonnecting-rod, S, is pi"- oted, the forward end of which connectingrodis pivoted between the lips upon the rear end of the nozzle-tube. Itwill now be seen that when the funnel-shaped nozzle is inserted into theend of a flue, and the steam-hose is connected with the boiler, thestop-cock which prevents the steam from passing out of the steam-tubemay be turned by pressing the steam tube into the nozzle -tube, pressingagainst the spiral spring, which will cause the connecting-rod to turnthe arm of the stopcock rearward, opening the cock and allowing thesteam to rush out through the nozzle into the flue, cleaning the same.hen the pressure upon the handles upon the steamtube is released, thespring will force the steam-tube rearward, closing the stop-cock, and itwill be seen that by adjusting the collar, against which the springbears, upon the steam-tube, the tension of the spring may be increasedor decreased at will.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a flue-cleaner, the combinationof a tube having a funnel-shaped nozzle at its end, and having alongitudinal slot, a stea1n-tube having a handle at its rear end and atits middle, having a hose connecting it with the boiler, and having ascrew at its forward end, sliding in the slot of the nozzle-tube, astopcock having a projecting arm, a connectingrod hinged or pivoted tothe arm of the stop-cock and to the rear end of the nozzle-tube, and aspring bearing against the rear end of the nozzle tube and against anadjustable collar upon the steam-tube, as and for the purpose shown andset forth.

, 1n testimony-that I claim the foregoing as my own I have hereuntoaiiixed my signature in presence of two witnesses.
